PROBLEM TO BE SOLVED: To provide a compact cooling device contrived to restrain noise and dust in liquid crystal display equipment and guarantee the quality of a liquid crystal panel. SOLUTION: As constitution for thermally connecting a plurality of light receiving members to make a coolant flow in a peripheral area other than a light transmission area on the liquid crystal panel or a polarizing plate for generated heat on the liquid crystal panel or the polarizing plate by a light source, a heat-of-vaporization cooling system in which an atomization member for atomizing the coolant is provided is applied to either heat receiving member, and a liquid cooling system in which the liquid coolant is circularly driven is applied to the other, and the heat receiving members by both systems are constituted of a coolant circulation system by one heat radiation member.
